A burner photocell (QRB1 / QRB2) is a flame detection sensor used in oil and gas burner systems. Its job is to detect the presence of a flame in the combustion chamber and send a signal to the burner control system. If no flame is detected when there should be one, the control system shuts down the burner for safety.

A burner photo cell (flame sensor) like the QRB1 is a photo‑resistive flame detector used in oil burner combustion systems to monitor the presence of a flame during operation. It’s an essential safety component in boiler, furnace, and industrial burner controls.
👁️ How It Works

The photo cell contains a light‑sensitive element (typically a photoresistor) that changes its electrical resistance based on the light intensity from the flame.

When the burner ignites and a stable flame is present, the photo cell detects the visible light emitted
